Abstract: In a procedure for filtering lime sludge meant to be regenerated to lime. Lime sludge is produced in the causticizing process in a sulphate cellulose mill, where it can be reused after regeneration to lime. In the procedure, lime sludge suspension is filtered on a filter drum in continuous rotation by depositing lime sludge on the drum and detaching part of the superficial layer of the lime sludge on the drum with a scraper so that the deeper lime sludge layer on the drum, which by-passes the scraper, serves as filtering medium for the superficial layer that is detached (as a so-called pre-coat). The purpose is to arrange the control of the filtering process so that the dry matter content of the lime sludge detached from the drum is substantially constant, and its essential feature is that the dry matter content of the lime sludge detached from the drum is followed so that when the dry matter content tends to decrease, the speed of rotation of the drum is first raised within a given control range and, after the control range has been used up, the scraper is moved closer to the surface of the drum so that at least part of the deeper lime sludge layer on the drum, serving as filtering medium, is detached and, if the scraper is returned to its earlier position, is replaced with a new lime sludge layer, whereupon the control is again continued with the aid of the drum's speed of rotation.

Abstract: A compact fluorescent tube comprises at least one U-shaped main tube part (11) and a base (12). Each main part has two straight tubular legs (14) of circular cross-section and a connecting tube (15) of rectangular cross-section. The connecting tube is joined to the cylindrical peripheral surface of respective tubular legs at regions adjacent the ends of the legs. The end surfaces (16) and one side (17) of the connecting tube form together a coherent flat end surface (18) on the U-shaped main part of the tube. A suitable method for manufacturing such a compact fluorescent tube comprises heating and bending straight glass tubes into U-shaped main tube parts, and blow moulding to form the connecting tube between the legs. Bending is effected around a first mould part which exhibits a channel-shaped abutment surface or accommodating the glass tube. A second, complementary mould part is provided for shaping the outer peripheral surface of the glass tube. The mould parts are caused to move relative to one another, such that the molten glass in the U-bend can collect in a dish-shaped part located in the second mould part. Finally, gas under pressure is introduced into the glass tube, so as to press the tube against the mould walls, such that the main tube parts are given their final shape.

Abstract: The invention relates to a spacing member arranged between a securing element (fixture) (13) implanted in the facial bone (the cranium) and an extraoral prosthesis, in particular a facial prosthesis. The spacing member comprises a base portion (1) intended to cooperate with the upper portion of the securing element (13), and an extension part (8,8') which forms an attachment point for the prosthesis (11). The extension part (8,8') is designed in such a way that it permits attachment of the prosthesis in a direction (10a,10a') (attachment direction) which forms essentially a right angle to the longitudinal direction of the extension part (8,8'). The spacing member combines the two conflicting requirements which exist particularly in the case of an orbital prosthesis, namely secure anchoring in the bone (radial attachment of the securing elements) and a more favourable attachment direction (10a,10a') (axial) for the prosthetic work. <IMAGE>

Abstract: In the disclosed method of determining the current or instantaneous operating conditions of a centrifugal pump, the radial forces impressed on the impeller shaft by the operatively rotating pump impeller are measured at a shaft-supporting bearing disposed proximate the pump housing and impeller. In a preliminary or test operation of the pump, this radial force measurement is taken at a plurality of volumetric liquid flow rates through the pump so as to develop a relationship between the radial force and liquid flow. Then, during normal operation of the pump, the current or instantaneous radial force is measured at the bearing and this measurement is compared to the previously-developed relationship to accurately determine the instantaneous operating conditions of the pump by identifying the point along the pump's characteristic curve-which defines for the pump a relationship between lifing height and volumetric liquid flow-at which the pump is currently operating.
